' s meness.

To clllwhom itmwysconcem:

Be it'known that we, THOMAS E. ,Fqwiinn,

a citizen of the United States, ,residing at and the combination andarrangement of parts hereinafter described and claimed.

The-object otthe invention is to provide a more simple and reliablemeans for feeding an acid and water or other exciting fluid upon a metalto produce flour bleaching fumes.

The above and other objects of the invention are attained in theprefer'redembodiment of the same illustrated in the drawings,

in whicha Figure 1 is a view partly in elevation and partly in section'of our improved gas gen- 2 for water or an determined rates throuorator; and Fig. 2 is a similar sectional view showing a slightlymodified form of the,

invention. a t

The. as generator com rises a receptacle 1 for mtric or' other aci and arece tacle other liquid whic will serve to increase t e action 'oftheacid upon zinc or other metal in the production of flour bleachingfumes. The liquids in these receptacles are fed drop1 by dropatpredischarge siphons 3, 4 which discharge into a funnel 5 arranged atthe upper end of a downwardly inclined receptac 6 in which the metal 7is su ported. The latter is I referablyin t e form of one or more ms ofzinc or other suitable metal arranged longitudinall upon the inclinedbottom" of the receptace 6 so that the acid and" water passing throughthe receptacle will "act upon said rods.

' Beneath the lower open end of the receptacle 6 is a collecting orwaste receptacle 8. The siphons 3, 4 are carried by controlling floats9, 10 arranged in the receptacles 1, 2, respectively, and they are adustably mounted upon the floats so that their rate of discharge may bereadily regulated and will be uniform as the floats lower in theSpecification-bi Letters Patent.

The siphon-27 discharges into a waste pipe 29. Itwill be seen t lower as the water or other liquid in the receptacle 25is discharged from-the si hon 27 and that since the-siphon 3? is carrieby said rece tacle 1 at a redetermined rate. a T e fumes pro uced by theaction of the acid andrwater upon the metal in the receptacle 6 passthrougha fume conductor 30 to the eye of a rotary fan 31 driven by abelt 32 from a power wheel 33and adapted to discharge into a flouragitator or chute 34 of any suitable form and construction. 7

I Having thus described our invention what we claim is:

1. A gas generator of the character deat the float 24,will,

receptacle, a float in the latter, an upright guide rod upon the float,a vertically adjustable member slidable upon said guide rod' and asiphon carried by said member and adapted tocontrol the flow of liquidfrom the liquid receptacle into the first mentioned receptacle.

2. A gas generator of the character described comprising a receptaclefor the solid substance entering into the reaction, a liquid receptacle,a float in the latter, an upright guide upon the float, a membervertically slidable upon said guide, a set screw for securing saidmember in an adjusted position and a siphon carried by said member andadapted'to control the flow of the liquid from the liquid receptacle tothe first mentioned receptacle.

3. A gas generator of the character de-.

scribed comprising a receptacle for the solid substance entering intothe reaction, a liquid receptacle, a float in the latter, anuprightguide rod upon one side of the float, an upright rod upon the other sideof the same and adapted to counterbalance the float and serve as ahandle, a clamp vertically adjustable upon said guide rod, a siphoncarried by the clamp and adapted to control the passageof liquid fromthe liquid receptacle to the first 4. A gas generator for a flourbleaching apparatus comprising a receptacle for the metal, an acidreceptacle, a float in the latter, a receptacle for an exciting fluid, afloat in the last mentioned receptacle, upright guides upon said floats,and discharge siphons vertically adjustable upon said upright guides and1 adapted to discharge into the receptacle for the metal.

5. Agas generator of the character described comprising a receptacle forthe solid substance entering into the reaction, a liquid 2 receptacle,afloat in the latter, an upright guide rod upon one side of the float,an upright rod upon the other side of the same and adapted tocounterbalance the float and serve as a handle, a clamp verticallyadjust- I able upon said guide rod, and a siphon carried by the clampand adapted to control the passage of liquid from the liquid receptacleto the first mentioned receptacle.

In testimony whereof we hereunto aflix our signatures in presence of twowitnesses.
